Blue flag iris

If you’re like most landscapers, you may have very little green thumb when it comes to growing perennials and flowers. If you want to plant perennials and flowers for your yard or garden, you’ve come to the right place. Keep reading to find out how to care for these plants so they will flourish and look stunning this spring.Iris versicolor is a flowering herbaceous perennial plant, growing 10–80 cm (4–31 in) high. It tends to form large clumps from thick, creeping rhizomes. The unwinged, erect stems generally have basal leaves that are more than 1 cm (1⁄2 in) wide. Leaves are folded on the midribs so that they form an overlapping flat fan. The well developed blue flower has 6 petals and sepals spread out nearly flat and have two forms. The longer sepals are hairless and have a greenish-yellow blotch at their base. The inferior ovary is bluntly angled. Flowers are usually light to deep blue (purple and violet are not uncommon) and bloom during May to July. Fruit is a 3-celled, bluntly angled capsule. The large seeds can be observed floating in fall.


This is a showy native iris of northeastern wetlands. Insects attracted to the sepals must crawl under the tip of a style and brush past a stigma and stamen, thus facilitating pollination. A similar southern wetland species, occurring from Virginia to Florida and Texas, is Southern Blueflag (I. virginica). It is a smaller plant, to 2' (60 cm) tall, with bright green leaves that often lie on the ground or water. A coastal, brackish-water species, Slender Blueflag (I. prismatica) has extremely narrow, grass-like leaves that are less than 1/4" (6 mm) wide; it occurs from Maine to Georgia and Tennessee. The name "flag" is from the middle English flagge, meaning "rush" or "reed.Debra LaGattuta is a gardening expert with three decades of experience in perennial and flowering plants, container gardening, and raised bed vegetable gardening.

It is a clump-forming plant with bluish-green, sword-shaped leaves. Its stalks each bear three to five violet-blue flowers with purple veining and a central yellow and white patch. The flowers span up to four inches (10.2 centimeters) in diameter, making them an eye-catching addition to any garden.This type of iris is considered a marginal aquatic plant, meaning it grows around the edges of water rather than in deep water. It can tolerate standing in as much as six inches (15.2 centimeters) of water, and it can survive being completely submerged for a short period, such as in a flood. It also can tolerate dry spells, though it would prefer to remain consistently moist. Provide a shallow layer of mulch around the plant to retain moisture if necessary, and give it a good watering if the soil dries out. (Source:www.thespruce.com)
